I have never purchased anything duty-free before but I'm planning to before my flight to the US (where I'm a citizen).
However, I'm leaving the airport for a hotel. I don't normally check a bag. What can I expect with my duty-free alcohol purchase? Can I bring it back in the duty-free bag and keep it on my carry on for my second, domestic leg?
Or should I plan on checking a bag for the domestic leg with the alcohol?
